Abstract
Two approaches to the analysis of spatial electrocardiographic vectors are currently being used: construction from the conventional ECG leads, and measurements from oscilloscopic recordings of spatial loops. There are several fundamental differences between the approaches, and there is no a priori certainty that equivalent or even similar phenomena are being investigated. This study presents a statistical comparison between mean spatial vectors, constructed from the conventional ECG, and instantaneous maximum spatial vectors, determined with the stereovector electro-cardiographic technic.
